This invention relates to machines forslicing meat and other materialhaving areciprocating table for presenting the'material to the slicingknife.

The object of the lnvention is to provide means for readilydisconnecting the driving Fig. 2 is a transverse section substantiallyon the line 1-1 of Fig. 1;

Fig. 3.is an elevation ofthe clamping device for locking the drive tothe reciprocating table; H

Fig. 4 is a side elevation of the device shown in Fig. 3; and

Fig. 5 is atop plan view of the device shown in Fig. 3 with a bufiermember carried thereon.

In the operation of slicing machines having rotary slicing knives andreciprocating tables it is sometimes desirable to be able to operate thedrivingmechanism without reciprocating the table. For instance, duringthe grinding of the slicing knifethere may be dustfrom the grindingwheels which would fall upon the parts of the table or upon the meatcarried by .the table if the table were permitted to continue itsreciprocating movement past the slicing knife. If the table can beconveniently disconnected from its driving mechanism and permitted toremain at the forward end of itspath of movement. the table and thematerial carried thereby will not be subjected to the dust from thegrinding wheels. This is referred to as an example of one occasion whenit is desirable to disconnect the reciprocating'table from its drivingmechanism. Many other occa sions mav arise when it will be advantageousto disconnect these parts. 7

Referring morespecificallv to the drawings. the numerals 1 and 2designate the guide bars or ways on whichthe recipro' 9 to the knifespindle, not shown. The upcating table 3 is mounted to'slide. Themachineis provided with the usual rotary slicing knife 4, base orsu'pportingframe 5 and hand wheel 6.". The base 5 carries'the usualupright studshaft having a beveled gear 7 mounted thereon drivenby abeveled pinion 13 securedto the end of the main drive shaft 12. Theknife 4 is connected to the-gear 7 by a shaft 9, pinion. 8, and theusual connection extending upwardly from the shaft right shaft connectedto the gear 7 carries a crank arm 10 tothe end of which the connectingrod 11 is journaled in the usual manner. The opposite end of the crankarm 11 instead of being pivoted to the forward cor her of theslidingtable 3 in the usual way,"

is pivotally connected to a swinging arm 14' having the opposite endpivotallv mounted FPATENTTOFFICE...

on the lower side of the table 3. The ends of the connecting rod 11 andarm 14 are pivoted together by means ofa hollow pivot pin 29. as shownin Fig.4. This pin has perfoe rated plugs threaded'into the oppositeends thereo throughwhich pins 15 and 16 pro ject. The pins 15 and 16have po nted outer ends and are pressed outwardlv by means of a springinterposed between the inner ends of the pins. The lower faceofthe-reciprocating table 3 at the forward corner thereof is provided withatapered recess for receivin the pointed end. of the pin 15., as shown nFig. 2, and a bearing plate 17 isprovided having a tapered recess in itstop face disposed in alinement with the recess, in the lower face of thetable,3. I

. The be ring plate 17 is slidablv mounted between the arms of an H-shaned supporting b acket 27 secured to the table 3. as shown in Figs. 1.2 and 4. Guide p ns 20 and 21 are fixed. to the upperfaee of the'bearingplate 17, and are guided in openings in the crossbar 22 of the bracket27. The table 3 is provided with openings for receiving the ends of thepins 20 and 2 1. Springs 23 and 24 surround the pins 20 and 21 and tendto force the hearing plate downwardly. A cam 19 is its operativeposition-the end of the connecting link 11 extends between the corner ofthe pins 15. and 16 extend into their respective table 3 and the bearingp1ate'17 so that the recesses so that the end of the connecting bar 11is pivoted to the corner of the table. The arm 14: swings about itspivotal support, as shown in broken lines in Fig. 1, to permit'theconnecting link to take" this position. The bearing "plate 17 is pressedupwardly by the cam 19 and handle 18 to hold the pins 15 and 16 in theirsockets. lVhen it is desired to release the table 3 from its drivingconnection, it is only necessary to swing the arm 18, as indicated bythe arrow in Fig. 4, until the restricted portion of the .cam engagesthe bearing plate .17. The springs 23 and 24 will force the bearingplate downwardly, releasing the pins 15 and 16 from their sockets sothat the table 3 will remain stationary. and operation of the drivingmechanism will only serve to swing the arm 14L about its pivotalsupporton the table 3. When it is desired to re-engage the table with itsdriving mechanism, it is only necessary to shove the table.

rearwardly until the pins 15 and 16 enter between .the bearing plate 17and the portion of the table 3 provided with the recess for the pin 15.i The bearing plate 17 may be beveled on its forward edge, as shown at28, to

assistin. lifting the pivotally connected heads of the bars 11 and 1ainto position between the bearing block and table. Abuil'er 25 may beconnected to the bracket 27 for engaging the heads of the arms 11 and 14when the table is. moved forwardly to bring the parts into position tobe clamped together. The table may be connected up with the connectingrod 11 at any position in the path of travel of the table The connectionand disconnection is readily made since it is only necessary to swingthe arm, 18 to clamp or unclamptlie head of the connecting rod 11 tothetab e 3. Nhcnthe parts are disconnected the rod 11 is supported by thearm 14 and is guided in a fixed pathof movement during operation of thedriving parts so that no parts are left loose to, be injured orv damagethe machine.
